A man who fatally shot his adult son in Washington County acted in self-defense and will not face criminal charges, prosecutors said Friday.

Stanley Laybourn, 65, of Cope, will not be charged in the death of his son, 31-year-old Leyton Laybourn, according to the Weld County District Attorney’s Office.

Stanley Laybourn is the husband of a Washington County commissioner. The Weld County district attorney was appointed special prosecutor in the case because of the relationship between Stanley Laybourn, his son, and the county commissioner, according to a news release.

Stanley Laybourn was initially charged with second-degree murder. The incident was investigated by the Colorado Bureau of Investigation.

Just before 8 p.m. on Aug. 13, Stanley Laybourn, who is disabled and partially paralyzed, was “forcefully pushed” into a planting pot by Leyton Laybourn. While on the ground, Stanley Laybourn shot his son once in self-defense, the release said.

Leyton Laybourn was taken to Yuma District Hospital, where he died later that night.

“When determining whether to file charges, we must wait on a complete and thorough investigation,” District Attorney Michael Rourke said in the release. “After looking at the evidence provided by CBI, all signs point towards self-defense.”

The charges against Stanley Laybourn were dismissed on Friday afternoon.
